TECHNICAL FIELD

The present disclosure relates to the field of optical lens, and moreparticularly, to a camera optical lens suitable for handheld terminaldevices such as smart phones or digital cameras and camera devices suchas monitors or PC lenses.

BACKGROUND

With the emergence of smart phones in recent years, the demand forminiature camera lens is increasing day by day, but in general thephotosensitive devices of camera lens are nothing more than ChargeCoupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor(CMOS sensor), and as the progress of the semiconductor manufacturingtechnology makes the pixel size of the photosensitive devices becomesmaller, plus the current development trend of electronic productstowards better functions and thinner and smaller dimensions, miniaturecamera lenses with good imaging quality therefore have become amainstream in the market.

In order to obtain better imaging quality, the lens that istraditionally equipped in mobile phone cameras adopts a three-piece orfour-piece lens structure, or even five-piece or six piece lensstructure. Also, with the development of technology and the increase ofthe diverse demands of users, and as the pixel area of photosensitivedevices is becoming smaller and smaller and the requirement of thesystem on the imaging quality is improving constantly, a seven-piecelens structure gradually appears in lens designs. Although the commonseven-piece lens has good optical performance, its settings onrefractive power, lens spacing and lens shape still have someirrationality, which results in that the lens structure cannot achieve ahigh optical performance while satisfying design requirements forwide-angle and ultra-thin lenses having a big aperture.

DESCRIPTION OF EMBODIMENTS

The present disclosure will hereinafter be described in detail withreference to several exemplary embodiments. To make the technicalproblems to be solved, technical solutions and beneficial effects of thepresent disclosure more apparent, the present disclosure is described infurther detail together with the figure and the embodiments. It shouldbe understood the specific embodiments described hereby is only toexplain the disclosure, not intended to limit the disclosure.

Embodiment 1

Referring to FIG. 1, the present disclosure provides a camera opticallens 10. FIG. 1 shows the camera optical lens 10 according to Embodiment1 of the present disclosure. The camera optical lens 10 includes 7lenses. Specifically, the camera optical lens 10 includes, from anobject side to an image side, an aperture S1, a first lens L1, a secondlens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixthlens L6 and a seventh lens L7. An optical element such as a glass plateGF can be arranged between the seventh lens L7 and an image plane Si.The glass plate GF can be a glass cover plate or an optical filter. Inother embodiments, the glass plate GF can be arranged at otherpositions.

In present embodiment, the first lens L1 has a positive refractivepower, and has an object side surface being a convex surface and animage object surface being a concave surface; the second lens L2 has anegative refractive power, and has an object side surface being a convexsurface and an image object surface being a concave surface; the thirdlens L3 has a positive refractive power, and has an object side surfacebeing a convex surface and an image object surface being a concavesurface; the fourth lens L4 has a positive refractive power, and has anobject side surface being a convex surface and an image object surfacebeing a convex surface; the fifth lens L5 has a negative refractivepower, and has an object side surface being a concave surface and animage object surface being a convex surface; a sixth lens L6 has apositive refractive power, and has an object side surface being a convexsurface and an image object surface being a concave surface; and theseventh lens L7 has a negative refractive power, and has an object sidesurface being a convex surface and an image object surface being aconcave surface.

Here, a focal length of the camera optical lens 10 is defined as f in aunit of millimeter (mm), a focal length of the third lens L3 is definedas f3, and a focal length of the sixth lens L6 is defined as f6. Thecamera optical lens 10 should satisfy following conditions:15.00≤f3/f  (1); and2.50≤f6/f≤5.00  (2).

The condition (1) specifies a ratio of the focal length of the thirdlens L3 and the focal length of the camera optical lens 10. This leadsto the appropriate distribution of the refractive power for the thirdlens L3, thereby facilitating improving the optical performance of thecamera optical lens 10.

The condition (2) specifies a ratio of the focal length of the sixthlens L6 and the focal length of the camera optical lens 10. This leadsto the appropriate distribution of the refractive power for the sixthlens L6, thereby facilitating correction of aberrations of the cameraoptical lens and thus improving the imaging quality.

In this embodiment, with the above configurations of the lensesincluding respective lenses (L1, L2, L3, L4, L5, L6 and L7) havingdifferent refractive powers, there is a specific relationship betweenfocal lengths of the third lens L3 and the camera optical lens 10 andthere is a specific relationship between focal lengths of the sixth lensL6 and the camera optical lens 10. This leads to the effectivedistribution of the refractive power of the third lens L3 and therefractive power of the sixth lens L6, thereby facilitating correctionof aberrations of the camera optical lens. Thus, the camera optical lenscan achieve a high optical performance while satisfying designrequirements for wide-angle and ultra-thin lenses having a big aperture.

In this embodiment, the first lens L1 has a positive refractive powerand a focal length of f1; the second lens L2 has a negative refractivepower and a focal length of f2; the third lens L3 has a positiverefractive power and a focal length of f3; the fourth lens L4 has apositive refractive power and a focal length of f4; and the fifth lensL5 has a negative refractive power and a focal length of f5, where f1,f2, f3, f4 and f5 satisfy the following condition of:10.00≤|f1+f3+f4|/|f2+f5|≤20.00  (3).

The condition (3) specifies a ratio of an absolute value of a sum of thefocal length f1 of the first lens L1, the focal length f3 of the thirdlens L3 and the focal length f4 of the fourth lens L4 to an absolutevalue of a sum of the focal length f2 of the second lens L2 and thefocal length f5 of the fifth lens L5. This can facilitate improving theimaging quality of the camera optical lens.

In an example, a curvature radius of the object side surface of thethird lens L3 is defined as R5 and a curvature radius of the image sidesurface of the third lens L3 is defined as R6, where R5 and R6 satisfy acondition of:(R5+R6)/(R5−R6)≤−20.00  (4).

The condition (4) specifies a shape of the third lens L3. Within thisrange, a development towards wide-angle lenses having a big aperture canalleviate a deflection degree of light passing through the lens, therebyeffectively reducing aberrations.

In an example, the focal length of the second lens L2 is defined as f2in a unit of millimeter (mm), and f2 and f satisfy a condition of:−15.00≤f2−f≤−11.00  (5).

The condition (5) specifies a difference between the focal length f2 ofthe second lens L2 and the focal lens f of the camera optical lens 10.This can facilitate improving the imaging quality of the camera opticallens.

In an example, a curvature radius of the object side surface of thefifth lens L5 is defined as R9 and a curvature radius of the image sidesurface of the fifth lens L5 is defined as R10, where R9 and R10 satisfya condition of:−10.00≤(R9+R10)/(R9−R10)≤−6.00  (6).

The condition (6) specifies a shape of the fifth lens. This caneffectively correct aberrations caused by the first four lenses (L1, L2,L3 and L4) of the camera optical lens.

In an example, an on-axis thickness of the first lens L1 is defined asd1, an on-axis distance from the image side surface of the first lens L1to the object side surface of the second lens L2 is defined as d2, andd1 and d2 satisfy a condition of:9.00≤d1/d2≤12.00  (7).

The condition (7) specifies a ratio of the on-axis thickness of thefirst lens L1 to the on-axis distance from the image side surface of thefirst lens L1 to the object side surface of the second lens L2. This canfacilitate processing and assembly of the lenses.

In addition, a surface of a lens can be set as an aspherical surface.The aspherical surface can be easily formed into a shape other than thespherical surface, so that more control variables can be obtained toreduce the aberration, thereby reducing the number of lenses and thuseffectively reducing a total length of the camera optical lens accordingto the present disclosure. In an embodiment of the present disclosure,both an object side surface and an image side surface of each lens areaspherical surfaces.

It should be noted that the first lens L1, the second lens L2, the thirdlens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6 andthe seventh lens L7 that constitute the camera optical lens 10 of thepresent embodiment have the structure and parameter relationships asdescribed above, and therefore, the camera optical lens 10 canreasonably distribute the refractive power, the surface shape, thematerial, the on-axis thickness and the like of each lens, and thuscorrect various aberrations. The camera optical lens 10 has Fno≤1.70. Atotal optical length from the object side surface of the first lens toan image plane of the camera optical lens along an optic axis (TTL) andan image height (IH) of the camera optical lens 10 satisfy a conditionof TTL/IH≤1.56. The field of view (FOV) of the camera optical lens 10satisfies FOV≥76.6 degrees. This can achieve a high optical performancewhile satisfying design requirements for wide-angle and ultra-thinlenses having a big aperture.

In an example, inflexion points and/or arrest points can be arranged onthe object side surface and/or image side surface of the lens, so as tosatisfy the demand for the high quality imaging. The description belowcan be referred to for specific implementations.
